Warning and Safety instructions

12

Correct installation

 Do not install this dishwasher in an area where there is a risk of explosion or freezing

conditions.

 To ensure stability a built-under dishwasher must only be installed beneath a continuous

worktop that is bolted to the adjacent cabinetry.

 In order to reduce the risk of damage from condensation, the furniture in the area

around the dishwasher should ideally be designed for commercial use.

Furniture can be protected using the vapour protection set, which is available as an op-

tional accessory.

The vapour barrier film should be stuck under the worktop in the area around the dish-

washer door.

Technical safety

 This dishwasher must only be commissioned, repaired and maintained by the Miele

Customer Service Department, a dealer or a suitably qualified service technician. Unau-

thorised installation, maintenance and repairs can cause considerable danger for the user.

 Before using the dishwasher, check it for any externally visible damage. Do not use a

damaged dishwasher. This could be dangerous.

 In the event of a damaged or leaking dishwasher, switch off at the power supply imme-

diately and call the Miele Customer Service Department, a Miele dealer or a suitably quali-

fied service technician.

 Faulty components must only be replaced by genuine Miele original spare parts. Only

when these parts are fitted can Miele guarantee the correct functioning and safety of the

appliance.

 The electrical safety of this dishwasher can only be guaranteed when correctly earthed.

If in any doubt, please have the electrical installation tested by a qualified electrician.

 Please follow the advice on installation in these operating instructions and the installa-

tion plan.

 Before connecting the appliance, ensure that the connection data on the data plate

(voltage, frequency and fuse rating) match the mains electrical supply.

 There must be no electrical sockets behind the dishwasher. Danger of overheating and

fire risk if the dishwasher were to be pushed up against a plug. See “Electrical connection”.

 Do not connect the dishwasher to the mains electricity supply via a multi-socket unit or

an extension lead. These do not guarantee the required safety of the appliance (e.g.

danger of overheating).

 Never open the casing of the dishwasher. Any contact with live connections or tamper-

ing with the electrical or mechanical components of the dishwasher will endanger your

safety and may lead to appliance malfunctions.

 The dishwasher must not be used if the electrical connection cable is damaged. A dam-

aged connection cable may only be replaced by a suitable connection cable of the same

type. For safety reasons, such replacement may only be carried out by the Miele Customer

Service Department or a qualified service technician.

Warning and Safety instructions

13

 The dishwasher must be disconnected from the mains electricity supply before any

maintenance or repair work is carried out.

 The plastic housing of the water connection contains electrical components. It must not

be dipped in water.

 There are electrical wires in the water inlet hose. Do not shorten the water inlet hose,

even if it is too long.

Correct use

 This dishwasher is designed for operation with water and detergents suitable for use in

commercial dishwashers only. Organic solvents and flammable liquid agents must not be

used in it.

This could cause an explosion, damage rubber or plastic components in the dishwasher

and cause liquids to leak out of it.

 Only use detergents formulated for use in commercial dishwashers. Unsuitable deter-

gents could adversely affect components of the dishwasher or the load items.

 Do not sit, stand or lean on the opened door. This would tip or damage the dishwasher.

 After any plumbing work the water pipework to the dishwasher will need to be vented. If

this is not done, components can be damaged.

 Please be aware that the dishwasher may be operating at high temperatures. When the

door is opened there is a danger of burning or scalding. Items, baskets and inserts must

be allowed to cool down before they are unloaded. Any water remaining in containers

could still be very hot. Empty them into the wash chamber before taking them out.

 The water in the cabinet must not be used as drinking water.

 Pre-treating items (for example with washing-up liquid and other cleaning agents) as

well as some types of soiling and some cleaning agents can cause a build-up of foam in

the wash cabinet. Foam can have an adverse effect on the cleaning result.

 Foam escaping from the wash cabinet can cause damage to the dishwasher. If foam es-

capes the programme must be cancelled immediately and the appliance must be discon-

nected from the mains electrical supply.

 There may be a risk of slipping if liquid is spilt on the floor depending on the type of

flooring and footwear being worn. Keep the floor dry where possible and take care to clean

up any liquid spills straight away. Take the necessary precautions when cleaning up haz-

ardous substances and hot liquids.

 When using cleaning agents and specialised products, it is essential that the manufac-

turer’s instructions are followed. Cleaning agents must only be used for the purpose they

are designed for by the manufacturer to avoid any material damage or the occurrence of

strong chemical reactions (e.g. oxyhydrogen explosion).

 To avoid material damage and corrosion, do not allow any acids or solutions containing

chloride to get into the wash cabinet or onto the casing. Similarly avoid any ferrous materi-

als with a corrosive effect.

 Do not wash items soiled with ash, sand, wax, lubricating grease or paint in the dish-

washer. These materials will cause damage to the dishwasher.

Warning and Safety instructions

14

 Do not clean the dishwasher or near vicinity with a hose or a pressure washer.

 Ensure that the outer casing of the machine does not come into contact with solutions

or steam containing acid to avoid any corrosion damage.

 Be careful when sorting items with sharp pointed ends and positioning them in the dish-

washer that you do not hurt yourself or create a danger for others. Sharp knives, forks, etc.

should be placed in baskets with the pointed ends facing downwards.

Accessories

 Only use genuine Miele original spare parts and accessories with this dishwasher. Using

spare parts or accessories from other manufacturers will invalidate the guarantee and

Miele cannot accept liability.

 Only use Miele baskets and inserts with this dishwasher. Using baskets and inserts

made by other manufacturers, or making modifications to Miele accessories can cause un-

satisfactory cleaning results, for which Miele cannot be held liable. Any resultant damage

would not be covered by the guarantee.

Warning and Safety instructions

15

Warning signs and symbols attached to the dishwasher

Warning:

Observe the operating instructions!

Warning:

Danger of electric shock!

Warning: Hot surfaces:

It can be very hot inside the wash cabinet when the door

is opened!

Risk of being cut:

Wear cut-resistant protective gloves when transporting

and setting up the machine!

Disposal of your dishwasher

 For safety and environmental reasons, dispose of all chemical agents according to the

manufacturer's instructions and to safety regulations. Safety goggles and protective gloves

should be worn.

 Render the door lock inoperable to prevent children from accidentally locking them-

selves inside the machine. Ensure a safe removal and proper disposal of the dishwasher

(see “Caring for the environment”).

Caring for the environment

16

Disposing of the packaging mater-

ial

The packaging material is used for handling

and protects the appliance from transport

damage. The packaging material used is se-

lected from materials which are environ-

mentally friendly for disposal and can gen-

erally be recycled.

Recycling the packaging material reduces

the use of raw materials. Use material-spe-

cific collection points for valuable materials

and take advantage of return options. Your

Miele dealer will take the packaging material

away.

Disposing of your old appliance

Electrical and electronic appliances contain

many valuable materials. They also contain

certain materials, compounds and compon-

ents which were essential for their correct

functioning and safety. These could be haz-

ardous to human health and to the environ-

ment if disposed of with household waste or

if handled incorrectly. Please do not, there-

fore, dispose of your old appliance with

household waste.

Instead, please make use of officially desig-

nated collection and disposal points to dis-

pose of and recycle electrical and electronic

appliances in your local community, with

your dealer or with Miele, free of charge. By

law, you are solely responsible for deleting

any personal data from the old appliance

prior to disposal. You are legally obliged to

remove any old batteries which are not se-

curely enclosed by the appliance and to re-

move any lamps without destroying them,

where this is possible. These must be taken

to a suitable collection point where they can

be handed in free of charge. Please ensure

that your old appliance poses no risk to

children while being stored for disposal.
